We're dividing 69654837 by 399 
We want to divide 69654837 by 399.

Let's proceed to step 1:
6 divided by 399 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 399

Advancing to step 2:
If we divide 69 by 399, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 399

Step 3:
When dividing 696 by 399, we get 1 with a remainder of 297.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 399 from 696, we get 297.
Grab the next digit (5) from the dividend, add it to 297, then carry on: 2975 / 399

On to step 4:
399 goes into 2975 7 times with a remainder of 182.
The next digit of our result is 7. 
Result so far: 17.0
If we take 2793 away from 2975, we end up with 182.
Bring next digit (4) of the dividend behind the 182 and repeat the process: 1824 / 399

Let's proceed to step 5:
399 can be fit into 1824 4 times, resulting in a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
Subtracting 1596 from 1824 leaves us with 228.
Append the next digit (8) from the dividend to 228 and continue with: 2288 / 399

Moving on to step 6:
If we divide 2288 by 399, we get 5 and a remainder of 293.
Use 5 as the next digit of our solution. 
Result so far: 1745.0
If we take 1995 away from 2288, we end up with 293.
Take the next digit (3) from the dividend and append it to 293, then repeat: 2933 / 399

Moving on to step 7:
If we divide 2933 by 399, we get 7 and a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 17457.0
If we subtract 2793 from 2933, we get 140.
Take the next digit (7) from the dividend and append it to 140, then repeat: 1407 / 399

On to step 8:
1407 divided by 399 is 3 with a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 174573.0
Deduct 1197 from 1407 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 9:
The number 399 fits into 2100 5 times, leaving a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 174573.5
Deduct 1995 from 2100 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 10:
When dividing 1050 by 399, we get 2 with a remainder of 252.
The number 2 becomes the next digit in our result. 
Result so far: 174573.52
The remainder is 252 after subtracting 798 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
399 goes into 2520 6 times with a remainder of 126.
The next digit of our result is 6. 
Result so far: 174573.526
The remainder is 126 after subtracting 2394 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 12:
399 goes into 1260 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 174573.5263
Subtract 1197 from 1260 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 13:
If we divide 630 by 399, we get 1 and a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 174573.52631
Deduct 399 from 630 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 14:
When dividing 2310 by 399, we get 5 with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 174573.526315
Subtract 1995 from 2310 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 15:
When dividing 3150 by 399, we get 7 with a remainder of 357.
Write down 7 as next digit of the result. 
Result so far: 174573.5263157
Deduct 2793 from 3150 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 16:
399 goes into 3570 8 times with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 174573.52631578
Deduct 3192 from 3570 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

After the division, we end up with 174573.52631578 and a remainder of 3.78e-07.
